Application filed November 19, 1923. Serial No. 675,707.

To all whom t may concern.'

Be it known4 that I, DoNovni inwnY HUNT, a citizen of the United States,resid ing at Louisville, in the county of Jefferson and State ofKentucky, have invented new and useful Improvements in Heaters, of whichthe following isa specification.

This invention relates to heating apparatus for use in residences orother places and has for its object the provision oi' a novel deviceembodying gas burners for heating a blast of air which is conducted tothe rooms or other places to be heated.

An important and more speciic object is the provision of a device ofthis character having a peculiar circulation whereby none of the heatwill be wasted but all utilized to act upon the coils through which theVair passes so as to eii'ect rapid and positive heating.

An additional object is the provision ot' a device of this characterwhich will be simple and inexpensive in manutacture, highly eiiicient inuse, durable in service and a general improvement in the art.

Nith the above and other objects and advantages in view the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawings, inwhich:

Figure 1 is a vertical section through a device constructed inaccordance with my invention,

Figure 2 is an enlarged detail view through one of the burners, and

Figure 3 is a detail section illustrating a modification.

Referring more particularly to the drawings I have shown the device ascomprising an upstanding preferably cylindrical casing or shell 10mounted upon legs or other supports 11. lVithin thetop of this shell orcasing is a hemispherical distributor l2 from which lead pipes 13 whichextend to the various rooms or parts ot the building to be heated.

Vithin the top oit the casing 10 is a partition 12L which extends fromthe distributor 12 .to the wall of the casing 10 to define a chamber 12cwhich communicates with the interior of the casing 10 through openings121.V

Located within this casing and suitably supported therein is a coil 14including outer and inner pipe members 15 and 16 respectively, thelatter of which connects at its lower end with the outlet 17 of a blower18 driven in any suitable manner. The upper end of this inner pipe 16discharges into the bottom of the distributor 12 as shown at 16a. Theair inlet to the blower comprises a coil 19 which has its intake end 2Oat the upper portion or. the casing and which is arranged between theconvolutions of the coil 14, the lower end of this coil 19 leading intothe blower casing as shown at 21.4

Extending vertically along'one side or' the casing, exteriorly thereof,is a distributing gas Ypipe 22 connected with asuitable 'feed pipe 23.Extending into the casing are burners 24 which are connected with thepipe 22 and which are equipped with the usual mixer 25.v rPhe burners 24are located within the coil 14 between the outer and inner pipes 15 and16 thereof. Y

Located near the bottom of the casing are bowl shaped deflectors 26 atwhich terminate the lower ends of heat return pipes 27 which are curvedoutwardly away from the upper end of the coil 14 and which communi catewith the space between the coil pipes 15 and 16.

1n the operation it will be seen that the blower lwill suck in airthroughthe coil 19 and will discharge air through the pipe 16 ot thecoil 14. `illhen the burners 24 are in operation it is quite obviousthat heat is applied to the space between the pipes 15 and 16 and thiswill certainly operate to heat the current or blast oit' air passingthrough the pipe 16 which air is discharged into the distributor 12 fromwhence it is conducted through the pipes 13 to the rooms or other placesto be heated. The heat ascending through the coil 14 is not wasted butpasses through from the upper end of the coil 14 into and downwardlyalong thepipes 27. The heat issuing fromr the lower ends ot these pipesis deflected upwardly by striking against the deliectors 26 and thisheat then circulates through and about all the coils, assisting inVheating them. All products of combustion escape through a flue pipe orchimney 28 which communicates with the top of the casing.

In Figures 1 and 2 the members 14, 15, 16 and 24 are all illustrated asbeing circular in shape. lt is apparent that it is not necessary thatthese elements have this particular configuration and for example I haveshown, in Figure 3, corresponding elements 14k if M39-, ind 24?* which:ire arranged operate in the suine manner but rectangular in crosssection.

Vl.Vhile .l have shown and described the preferred embodiment of myinvention it is of course to be understood that l reserve the right toineke such changes in the forni, construction and arrangement oil partsas will not departroin the spirit of the invention or the scope oi' thesubjoined ciairns.
